*p ≤ 0.05; **p ≤ 0.01; ***p ≤ 0.001; r = Pearson product moment correlation coefficient; Beta = standardised regression coefficients. 1 Both direct and indirect measures of PBC and attitude (TPB) were included in this study as each have been used to measure these constructs in the literature. However, only the indirect, theoretically derived measures were included in these theoretical regression equations Similarly, Generalised Self Efficacy was included in this study because this is how some studies using SCT have interpreted and operationalised SE, however only the theoretical measure of SE is included in this theoretical regression equation. II is a post intention theory and so is not included in this analysis. |
